Review
The authors have responded satisfactory to most comments. Most importantly, they have included the possibility of partially engulfed morphologies in the discussion of the results. However, they are inaccurate in their reference to Reid et al. (2011). They added the following sentence to the revised manuscript:
“Reid et al. (2011) argue that core–shell morphologies are favored for a liquid phase surrounding a solid crystalline core.”
This citation is taken out of the context and needs to be revised. Within the context the sentence reads: “This is to be contrasted with the widely held assumption that core–shell morphologies are formed. While this assumption may be well founded for a liquid phase surrounding a solid crystalline core, this assumption cannot be made for aerosols containing discrete hydrophobic and hydrophilic liquid domains.”
The main topic of Reid et al. (2011) is indeed the morphologies of liquid-liquid phase separated particles. They investigated decane/aqueous sodium chloride droplets and found partially engulfed morphologies at high RH, in accordance with predictions based on surface and interfacial tensions. The morphology changed to core-shell when RH and the volume fraction of decane decreased. Given the larger size of PE compared with decane and the rather stronger salting-out effect of AS compared with NaCl, partially engulfed is the likely morphology for the PE/AS particles, however, the authors are right to point out that the line tension needs to be taken into account for smaller particles.

Dear authors,
Thanks for your response and the revised manuscript. The manuscript was seen by Referee 1, who satisfied with your revision, but still have one more minor comment. Please revise accordingly and I will proceed to final decision swiftly.

Organic compounds may form a barrier to condensation. Such barriers have been hypothesized to prevent water and other substances from mixing with salt cores. This will hinder the particles' ability to aid cloud formation of
